Description
Technical field
The utility model belongs to a kind of special equipment of component of machine processing industry, mainly is the boring processing at the cylinder cap camshaft deep hole in the engine manufacturing.
Background technology
In cylinder cap processing, the requirement on machining accuracy height, particularly aperture of cylinder cap camshaft hole is between φ 20～φ 40mm, and the degree of depth is between 450mm～550mm, divide 5 grades even more grades to be interrupted processing, there is big difficulty of processing in draw ratio greater than 10 deep hole, difficult machining hole.Traditional processing mode is that the drawback of existence is with horizontal boring machine boring processing: horizontal boring machine equipment is relatively more expensive, and the processing dimension shakiness is debugged more time-consuming.During the machining cam axis hole, at first to do one " cutter relieving " action, make boring cutter bar be offset a safe distance along boring cutter sword rightabout, after boring cutter enters the blank hole precalculated position, do " return " action again and promptly do oppositely moving of " cutter relieving " action, make the boring cutter axis get back to the position that overlaps with the cam shaft blank axially bored line, on horizontal boring machine, " cutter relieving → return " action, can be by main shaft along Z to moving or workbench is realized to moving along Y because lathe is the feed screw nut transmission, this dual mode, all be one just in motion process, one anti-motion, the round gap error that all has a leading screw and nut, and " return " manually controlled by the operator to the processing work tram, has an operate miss, two deviation accumulation stacks, cause mismachining tolerance, therefore, the camshaft hole dimensional accuracy of boring is not high, dimensional stability is bad, in addition, if operator's error, when machine tool chief axis " return ", depart from the camshaft hole axis based error when big, the debugging trouble.
Summary of the invention
Goal of the invention of the present utility model is to overcome the above-mentioned deficiency of prior art and provides a kind of machining accuracy height, convenient and practical boring to process the device of cylinder cap camshaft deep hole.
The technical scheme that the utility model is dealt with problems is: workbench is housed on the machine tool guideway; Be fixed with boring cutter supporting base, positioning fixture on the workbench; The boring cutter bar that connects machine tool chief axis is arranged on the boring cutter supporting base, the boring cutter sword is housed on the boring cutter bar; Be useful on the alignment pin of fixation workpiece, the workpiece pressuring clamping device of workpiece pressing and the opening of placement lifting platform on the positioning fixture; Be equipped with on the workbench and be used to drive the cam link rod that lifting platform is done the oscilaltion campaign, the cam link rod is connected with handle.
The pilot hole of assembling lifting platform is arranged on the described workbench, and lifting platform is assemblied in workbench through its lead, lead and workbench matched in clearance.
The essential distinction of the utility model and boring machine is: in the boring process, " cutter relieving → return " do not realized by machine tool motion, the gap error and the operate miss of the forward and reverse motion of lathe have been avoided, by the workpiece elevating movement, when " return ", workpiece drops on the positioning fixture automatically, positioning accuracy is guaranteed by positioning fixture, thereby guaranteed machining accuracy, the utility model has not only improved processing precision of products, and simple, convenient and practical, easy to manufacture, with low cost, in cylinder cap camshaft deep hole machining, can access widely and promote the use of.Be widely used in other similar deep hole boring processing.

The specific embodiment
Among Fig. 1, Fig. 2, on lathe 1 guide rail workbench 8 is housed.Be fixed with boring cutter supporting base 4, positioning fixture 7 on the workbench 8; The boring cutter bar 3 that connects machine tool chief axis 2 is arranged, 3 supports of 4 pairs of boring cutter bars of boring cutter supporting base, guide effect on the boring cutter supporting base 4.Boring cutter sword 5 is housed on the boring cutter bar 3.Be useful on the alignment pin 12 of fixation workpiece 6, the workpiece pressuring clamping device 14 of workpiece pressing 6 and the opening of placement lifting platform 10 on the positioning fixture 7.Be equipped with on the workbench 8 and be used to drive the cam link rod 11 that lifting platform 10 is done the oscilaltion campaign, the cam of cam link rod 11 pushes up mutually with lifting platform 10 lower planes.Cam link rod 11 is connected with handle 9.The pilot hole that assembling lifting platform 10 is arranged on the workbench 8, lifting platform 10 is assemblied in workbench 8 and can moves up and down lead 13 and workbench 8 matched in clearance through its lead 13.Processing work 6 clampings are on positioning fixture 7, by turning handle 9, double-linked cam link rod 11 rotates, and cam link rod 11 drives lifting platform 10 by eccentric center principle and does oscilaltion campaign, and processing work 6 is followed lifting platform 10 and moved up and down promptly " cutter relieving ← → return " and move.
Among Fig. 3, be fixed with boring cutter supporting base 4, positioning fixture 7 on the workbench 8, be useful on the fixedly alignment pin 12 and the workpiece pressuring clamping device 14 of processing work on the positioning fixture 7, it is handle that lifting platform 10 is loaded on workbench 8,9.
